When fields stay wet
NOVELTY, Mo. – Heavy rainfall is becoming more frequent across Missouri, leaving producers dealing with saturated soils, ponded fields and flooding even before the 2026 growing season began. Understanding how excess water affects crops—and what steps can help in the short and long term—can protect yield potential and improve field resilience, says University of Missouri Extension state soil science specialist Gurbir Singh.
Drainage water recycling systems improve corn yields
Drainage water recycling boosts corn yields, reduces variability, and protects water quality by reusing nutrients efficiently.
MU drainage system increases yields, reduces nutrient runoff
COLUMBIA, Mo. – University of Missouri agronomists found corn and soybean yields increase by 20 percent or more when they use drainage control systems, said Kelly Nelson, MU Extension agronomist at the Greenley Research Center, Novelty. A combination of drainage and subirrigation boosts corn yields by 45 percent and soybean yields by 20 percent in claypan soils, Nelson said. The Greenley system allows excess water to drain and be…
